Alla Lighting T25 3457 3157 Switchback LED Turn Signal Lights Dual Color 6000K White/Amber Yellow 12V 4157NAK 3457AK 4057 3057 3757AK 5702AK 4157AK Extremely Super Bright 2835 28-SMD Upgrade

I bought these a while ago back in early 2018 for my 2016 mustang gt premium. They worked great until I took them out for the opt7 sequential turn signals. Well I popped them back in because I had the opt7 sequential turn signals fail on me multiple times and I’m done not having a unreliable turn signal. And well sure enough when I popped these bad boys back in after sitting in the stock turn signal housing for over a year they work like they should. And they match the tri bar why better than the opt7 6000k. These are like a 4300k-5000k light temp. I’ll never buy anything from opt7 ever again. Horrible customer service and they wanted me to pay for shipping for the return and then on top of it all wanted me to pay for the new set up front and if they deem they are warranty worth they will issue a refund weeks from now. They are in the trash where they belong. I’m Done dealing with them. If you’re on the market for something different from stock get these. They are cheep, bright as hell “brighter than the opt7” and reliable from what I can tell. Plus one day shipping if not same depending on your area. Only good thing I got out of the opt7 was the resistor so my interior turn signal won’t sound like a running horse when trying to turn. At first years ago it didn’t bother me but months later it got real annoying so using the opt7 resistor on the stock wire harness worked great and the turn signal is normal.

Super bright. Color is poppin and switches flawlessly. Will buy more

These were exactly as described and actually worked better than expected. On my 2005 BMW 330ci, I used these to replace my front turn signals. I already had load resistors and had intended to use them...but I didn't have to! I simply plugged them in and got no hyper flash or warning lights on the dash as I had expected to be the case.They are bright, seem well-made, and fit snuggly in the socket. The color output is great.They are longer than most 7440/7443 bulbs so in some vehicles it does push the bulb past the focal point of the reflector/lens. However, because they are so bright and designed to provide over 180° field of view, it is kind of negated.As someone who has owned many, many sets of switchback bulbs and who tends to have a tendency to be picky, these are just great bulbs and they are priced reasonably.

I put these on my 94 ranger and they plug right in to factory plugs. They are bright for blinkers and very good quality. Highly recommend

I purchased these Alla Lighting LED's for my 2020 Jeep Gladiator, which came with halogen lighting from factory. On the Gladiator, the front lights consist of a DRL & parking light combo in one housing (using a 7443 dual-filament white lamp), while the turn sig's are a separate lamp (7440A single-filament amber lamp) in the adjacent housing.My intent was to use these LED bulbs for the DRL/parking lamp locations, and they do snap right in to the bulb holder, as designed . HOWEVER, once they were installed, I discovered that the DRL's were amber, and the parking lights were white... just the opposite of what was anticipated (and what is the norm for forward lighting).I debated upon returning them, but decided a simple modification the the OEM wiring (at the lamp socket) would correct the problem. I simply swapped the two "hot" wires feeding the socket, which then made the white light come ON in the DRL mode, and the amber light come ON in the parking mode. There are 3 wires at the socket: Ground wire (black); DRL wire (white/yellow stripe); Parking light wire (white/purple stripe). Swap the white/yellow & white/purple into the socket.Sooo... while Amazon says these will "fit" a Jeep Gladiator (and indeed they do fit the lamp socket and light housing), they will not operate with the correct colors in the "stock" configuration. A wiring change should be done to make the light colors correct for the application. Not a huge deal, but please be aware...

These DO NOT work as stated in the description for my 2013 Toyota Tundra. Both the DRL and turn signals are amber using the same circuit. Because the DRL's are on constantly, the required resistor needed gets to 350 degrees. The added resistor is designed to handle the momentary use of the turn signals which would not be an issue and allow the resistor to get so hot.I found a company from Washington called VLED and ordered resistor free bulbs from them. Yes, several times the cost but the company has quality products, has excellent customer support and won't melt your truck.

Very bright white and amber. Installed in my 2013 f150, with just the parking lights on, you can see the white shining on the ground.Got the rear lights from alla as well, and the only con I found with them, is the anti-hyperflash is useless. Still does it, but, I have found that you will need to upgrade your relays to a lesser resistance to get the proper blink pattern. Keep that it mind when you get these.

These lights did what I needed them to do, they work perfectly.Thank you!
